SODA-WATER APPARATUS.

Application filed March 29, 1924. Serial No. 702,770.

T 0 all whom may concern:

Be it known that 1, JAMES R. NEFF, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Tmprovements in Soda-Tater Apparatus, of which the following is a speci fication.

The object of this invention is to utilize the carbonic acid gas with which drinks ineluding soft-drinks under pressure are charged to cause them to effervesce in producing a live sparkling display in glass tubes, to attract attention of customers every ime a drink is drawn, and then to thoroughly cool the same charged liquid after it leaves the display tubes and before it reaches the discharge faucets.

This principal object, and other minor ones which will hereinafter appear, are accomplished by the apparatus illustrated in the accompanying drawing, in which Fig. 1, is a perspective view of my invention, and Fig. 2 is a vertical section of the ice cooler and associated parts, more or less diagrammatic in character, for the purpose of more clearly illustrating the operative arrangement.

A. base comprises a raised platform 3, on which a cooler is mounted. The cooler as here shown is octagonal, with two metal and six glass sides, but this shape may be varied at will without departing from the spirit of my invention. The sides are bound together by an upper metal band a, and like lower band 5, and all of the joints are made water tight.

/Vithin the cooler a closed metal cylinder 8, is located, around the outside of which a pipe 7, tinned as usual to prevent the contamination of the liquid circulated therein, is coiled in the manner shown. One end of the pipe 7 connects with the interior of the cylinder through the cylinder head, and the other end is bifurcated to serve two faucets 8 and 9, located on the outside of the cooler and supported by the sides 10, which are of metal for this purpose. The cylinder is charged through a supply pipe 11, that rises to a suitable distance above the cooler, and discharges into the top of a series of coils, the horizontal members 12 of which, are of glass, through which the effervescent liquid coming through pipe 11 from a suitable source (not shown) travels, and the lower end of the coil discharges through pipe 13, into and to thebottoin of the cylinder 8.

The space in the cooler around the cylinder 8 and the pipe coils surrounding the cylinder, is packed with broken ice to cool the carbonated liquid ready to serve through the faucets to customers.

Condensation gathers on the outer surface of the cooler and descends by gravity into an annular pan 15, here shown as an integral part of the base. The faucets 8 and 9 also drip into this pan.

The horizontal conduits 12, are preferably of glass for display purposes. The gas breaks up the liquid conducted through the conduits into innumerable ever-changing bub bles that present an active sparkling display that is very attractive to the eye. The liquid in some cases contains a syrup and a flavoring material which is often variously colored thereby adding variety to the display, and also requiring frequent cleansin of the glass tubes to keep them clear, an wholesome. The glass tubes are mounted in end fitings of metal through which the circuit is made from a higher to a next lower tube, at alternatly opposite ends of the tubes to compel uniform circulation. Horizontal tubes 16, of metal, form extensions of the glass conduits .12. One of these for each tubular unit, is closed by a screw cap 17, at its end, the removal of which cap affords entrance to the tube of a cleaning brush. The caps are preferably at each alternate opposite end of the horizontal units, in the manner shown.

In the operation of my display vending apparatus, carbonated liquid is supplied through the pipe 11, and passes through it through the top horizontal glass tube 12, thence successively through all of the tubes 12-, and on through the pipe 13, to the bottom of the cylinder 8, where it discharges into the cylinder. From the upper end of the cylinder 8 it passes out and through the pipe coil 7, to the faucets 8 and 9. When a drink is drawn from either faucet the pressure refills the apparatus, the sparkle is exhibited in the glass tubes, and then the liquid is cooled in the cylinder and pipe coils, packed in ice, before being served to customers. The capacity of the cylinder provides a reserve of cold liquid, which is necessary if the liquid is drawn off rapidly at the faucets.

Having thus fully described my invention,

What I claim as new and Wish to secure by Letters Patent, is

1. In a drink-vending device an ice receptacle, cooling coils in the receptacle, a supply pipe having a series of transparent display loops over the receptacle, means connecting it With the cooling coils, and dispensing means connected to the coils.

2. In a drink-vending device, an ice receptacle, With an internal supply tank, and surrounding cooling coils connected to the supply tank, a supply pipe leading to the supply tank, and dispensing means connected to the coils.

3. In a drink-vending device, an ice receptacle with an internal supply tank and surrounding cooling coils, connected to the supply tank, a supply pipe having a series of transparent display loops over the receptacle and leading to the supply tank, and dispens ing means connected to the coils.
